When DD was at nursery school she spent the entire year talking to her friends but no adults at all - not even once. Since starting reception in September she hasn't spoken to any other child, though she does have friends. She reads her words to her teacher one on one but doesn't speak at all all day other than that. At home she never stops talking and is very happy but she has been really despondent about going to school for the past few weeks and isn't enjoying it at all. Surely almost 2 years of not talking in a school environment is enough proof she isn't going to suddenly ''come out of her shell's and her teacher should do something?
